The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). In 1902 the Siemens company developed a tantalum lamp filament. From 1898 to around 1905 osmium was also used as a lamp filament. In 1906 the tungsten filament was introduced

These light bulbs are an alternative to the original halogen light bulbs Xenon light bulbs that uses xenon gas which produces a whiter light, and makes it more adaptable to the human eye. It gives of light color similar to daylight. Mainly used for lamps, cabnit lights, or fog lights. Xenon bulbs are twice as bright as the original halogen bulbs making it last tremendoous amounts of time. I also have a Xenon flashlight, never failed me.
Yes there was, more specifically it was made in 1800 by Humphry Davy. However later on Thomas Edison was experimenting with a great amount of filaments and found that the best one was a carbon filament. That light bulb would last over 1500 hours, compared to the previous 40.
No, not in the filament. You are probably thinking of compact fluorescent light bulbs, which do contain mercury.
In incandescent bulbs, gases (other than oxygen) prolong the life of the filament. In florescent bulbs, the gas takes the place of the filament.
